In addition, compared with exotic materials such as the III-V compounds or the insulator lithium niobate (LiNbO3), Si is a kind of well-understood and robust material, compatible with the manufacturing in the microelectronics industry and potential for straightforward integration with electrical components [10].
Equations (5) ~ (8) have taken the material dispersion and the waveguide dispersion of the SOI into account, thus the calculation is more reliable, which can achieve the reliable reference data for the actual production.
These periodic arrangements of different dielectric materials offer a huge potential to make wavelength selective optical devices be applied to the current WDM optical telecommunication networks.

Introduction Along with the rapid development of chemical industry, many industrial factories, tank farm and warehouse store with a lot of dangerous chemicals, most of the hazardous chemical materials of an inflammable, explosive, toxic and harmful and corrosive.
Switch type by NdFeB magnets is forever soft rubber materials, the balloon is by acid and alkali or corrosion resistant materials.
Adaptive strong magnetic emergency sealing device structure schematic drawing Soft rubber balloon(10) in the process according to the specific leaked medium and environment different, choose acid, alkali, corrosion resistant materials; Diversion ball valve (4) according to need to open or closed, direct drainage or blocking; Switch type ever magnet (9) NdFeB permanent magnetic materials selection of high energy made forever magnets, small volume, strong attraction.
Risk source leaking adaptive universal strong magnetic containment device, the rapid closure methods in the existing traditional blocking technology conditions, the NdFeB high-energy permanent magnetic materials for the switch type in produce magnets of magnetic flux, with strong suction of the switch on the permanent magnet, without external power control.

How to make full use of organic and inorganic sludge, sludge materials is a cost-effective use of resources approach.
The use of sludge materials generally can be attributed to the following: the system lightweight ceramic, made of molten material and the molten glass ceramics, production of cement and so on.
Most of the past with sludge incineration ash as raw materials to produce all kinds of building materials in recent years, in order to save investment (construction of incinerators), full use of the calorific value of the sludge itself, save energy, the direct use of sewage sludge as raw materials to produce all kinds of building materials technology has been developed [7].
High surface area materials prepared from sewage sludge-based precursors.

Magnesium alloy is the lightest metal that is used as a structural material.
As a result, majority of Magnesium were used for non-structural material of the addition element etc.
However, application of Magnesium alloy as the light weight and high strength material which takes the place of Aluminum alloy and Plastic has expanded to structural material such as aerospace structural member and vehicle components etc. by the advancement of molding method and coating technology [1].
Experimental device used in this research is Ballistic range (Institute of Fluid Science, Tohoku University) shown in Fig.1.
